  A clear embodiment of the present invention is illustrated through the above drawings and is described in further detail below. Such drawings and character descriptions are not intended to limit the scope of the present invention, but to allow those skilled in the art to understand the concept of the present invention by referring to specific embodiments. .

  According to an embodiment of the present invention, there is provided a file download method, an apparatus thereof, and a system thereof. When a mobile terminal needs to download a file, and there is a mobile terminal connected to the mobile terminal, the mobile terminal Files can be downloaded by mobile terminals connected to the server, that is, the server sends the subfiles obtained by dividing the files waiting for download to each mobile terminal, and after the download is completed, the connection between the mobile terminals The download waiting file is obtained by acquiring the subfile from each mobile terminal and merging. Since each mobile terminal downloads only a part of the file waiting for download, the mobile terminal can download the file in a short consumption time.

  As shown in FIG. 1, an embodiment of the present invention provides a file download method. The method is applied to a mobile terminal that requires file download, and includes the following steps.

  S101: When it is necessary to download a file by a mobile terminal connected to the mobile terminal, at least one mobile terminal that receives a file is determined from each mobile terminal connected to the mobile terminal that needs to download the file. .

  S102: Sending a request for split download of a file waiting for download to the server, so that the server sends the subfile obtained by dividing the file waiting for download to the mobile terminal receiving the file, or the mobile terminal and file receiving the file, respectively.・ Send to each mobile device that needs to be downloaded.

  S103: After the file receiving mobile terminal receives and completes the file, the sub-file received by the receiving mobile terminal is acquired.

  S104: After all the subfiles are acquired, the subfiles are merged into one file and stored.

  The file download method provided in FIG. 1 is based on a mobile terminal that requires file download. Each mobile terminal connected to a mobile terminal that requires file download may be a terminal connected to the mobile terminal that requires file download via a wired or wireless system, so that a resource-share mobile terminal can be realized. It was. Here, the wireless connection may be a Bluetooth (registered trademark) connection, an ad hoc wireless network (adhoc WiFi) connection, or the like. As a result, wireless connection with resource sharing between devices can be realized.

  When a mobile terminal needs to download a file, if there are a plurality of mobile terminals connected to the mobile terminal, the download may be performed by the mobile terminal connected to the mobile terminal. At this time, the mobile terminal that needs to download the file may determine at least one mobile terminal that receives the file from among the mobile terminals that are connected to the mobile terminal.

  After the mobile terminal that needs to download the file transmits a download request for dividing the file waiting for download to the server, the server receives the subfile obtained by dividing the file waiting for download, or the mobile terminal that receives the file. And file download to the mobile terminal that needs to be downloaded. For example, when the bandwidth of a mobile terminal that requires file download is relatively small, the mobile terminal that requires file download does not receive the file and the file is downloaded only by the mobile terminal that receives the file in order to improve the download speed. You may receive it.

  After the file receiving mobile terminal receives and completes the file, the mobile terminal that needs to download the file acquires the subfile received by the mobile terminal that has received the file. After the mobile terminal that needs to download the file acquires all the subfiles, the subfiles are merged into one file and stored. This makes it possible to download a file. Since each mobile terminal needs to download only one sub file, the mobile terminal can download the file in a short consumption time.

  As shown in FIG. 2, S101 may include S201 and S202.

  S201: A download request is transmitted to each mobile terminal connected to the mobile terminal requiring file download.

  S202: Until the waiting time reaches the maximum waiting time set based on the size of the file waiting for download, or the number of mobile terminals that have confirmed the file reception is the number of files received based on the size of the file waiting for download. Until the maximum number of mobile terminals is reached, receive the download acceptance response sent from each mobile terminal connected to the mobile terminal that needs to download the file. Confirm as

  Of course, those skilled in the art can determine at least one mobile terminal for receiving a file from each mobile terminal connected to the mobile terminal that needs to download the file using other possible forms. Although only one embodiment has been provided, each possible form is not described one by one.

  Furthermore, since the performance and bandwidth of each mobile terminal are different, the download speed of a mobile terminal with good performance is faster than the download speed of a mobile terminal with relatively poor performance, and the download speed of a mobile terminal with a large bandwidth is Since the download speed is relatively faster than the download speed of a relatively small mobile terminal, it is necessary to consider the device performance and bandwidth of the mobile terminal that receives each file when dividing the file waiting for download and distributing the download task. In the application, the request for split download of the file waiting for download includes the proportional relationship between the size of the file waiting for download and the device performance of the mobile terminal receiving the file, the size of the subfile after split determined based on the bandwidth, File size and file size Yl device performance of the receiving mobile terminal may also include a download mapping relationship between sub-file and the mobile terminal of the file received after the division was determined based on the bandwidth.

The server sends the subfile obtained by dividing the file waiting for download to the mobile terminal that receives the file, or sends it to the mobile terminal that receives the file and the mobile terminal that needs to download the file.
The server divides the file waiting for download into the same number of subfiles as the number of mobile terminals receiving the file based on the proportional relationship of the size of the divided subfiles, and each subfile corresponds in the download mapping relationship. It may be transmitted to the terminal.

  For example, if there are three mobile terminals for file reception, the performance of one mobile terminal is good, the bandwidth is large, the performance of the other two mobile terminals is relatively poor, and the bandwidth is also relatively If the download waiting file is divided, the download waiting file is divided into one large subfile and two small subfiles, and the large subfile is distributed to the mobile terminals with good performance. Two small subfiles can be distributed and downloaded to mobile terminals with relatively poor performance.

  Furthermore, when the download waiting file is divided, if the download waiting file is a video file, the divided subfile is a video segment, and after determining the proportional relationship of the size of the divided subfile, The download waiting file may be divided based on the time. One implementation is that the server determines the start time point and end time point corresponding to each video file segment to be cut based on the proportional relationship of the size of the subfile after division, and further saves it in the video file. The time stamp of the video frame and / or the audio frame corresponding to the start time point and the end time point corresponding to each video file segment to be cut is determined. Here, the time stamp of the video frame and / or the audio frame indicates a time point at which the video frame and / or the audio frame corresponds to the video file. Further, the time stamp of the video frame and / or audio frame stored in the video file is set to each video file segment to be cut based on the correspondence with the offset position in the video file of the video frame and / or audio frame. An offset position in the video file of the video frame and / or audio frame corresponding to the corresponding start time point and end time point is acquired. The server assigns to each video file segment to be cut based on the start time point corresponding to each video file segment to be cut and the offset position in the video file of the video frame and / or audio frame corresponding to the end time point. Video frame and / or audio frame data of a video segment between corresponding start time points and end time points is acquired. That is, each video file segment to be cut out is obtained.

  For example, in order to guarantee the overall download progress and improve the fluency of the entire download, the following is included after sending the download request for the download waiting file to the server.

  That is, if it is determined that there is a mobile device that receives a file with a download speed that is too slow, or if it is determined that there is a mobile device that receives a file that has a poor connection with its own mobile device, the download speed is too slow. Alternatively, a download end command is transmitted to the file receiving mobile terminal having a poor connection, and the corresponding sub file is set as a new download waiting file.

  In the actual application, download time is set for each file receiving mobile terminal, and when the download time is reached, a download progress inquiry request is sent to the file receiving mobile terminal, and a response that the download is too late is sent. If it is received or if a response of a mobile terminal that receives a file is not received within the set time, it is determined that the download speed of the mobile terminal is too slow, and a download end command is transmitted to Downloading is terminated, and the sub-file to be downloaded by the mobile terminal is set as a new download-waiting file and downloaded again.

  As shown in FIG. 3, when it is determined that there is a mobile terminal that receives a file whose download speed is too slow, or when it is determined that there is a mobile terminal that receives a file with poor connection with the mobile terminal, Sending a download end command to the file receiving mobile terminal whose speed is too slow or having a poor connection and making the corresponding sub-file a new download-waiting file includes the following steps.

  S301: Determine the download time of each file receiving mobile terminal based on the device performance of each file receiving mobile terminal.

  S302: When it is determined that a reception completion response has not been sent back from the mobile terminal receiving each file within the set download time, a download progress inquiry request is transmitted to the mobile terminal receiving each file.

  S303: When receiving a response indicating that the download transmitted from the file receiving mobile terminal is too late, or from the file receiving mobile terminal within a set time after transmitting a download progress inquiry request to the file receiving mobile terminal. Is not received, a download end command is transmitted to the mobile terminal that receives the file, and the corresponding subfile is set as a new download waiting file.

  Of course, those skilled in the art may employ other possible forms to guarantee the overall download progress. Here, each executable form is not described one by one.

  Here, after determining a new download-waiting file in S303, the mobile terminal that needs to download a file may request download of a new download-waiting file. For example, the download form of the new download waiting file may be determined based on the size of the new download waiting file. When a new file waiting for download is large, for example, when the number of bytes of the file is larger than the set minimum number of bytes of the file to be downloaded by the mobile terminal connected to the mobile terminal, connect to the mobile terminal. It may be determined that the file is to be downloaded by the mobile terminal, and the download is performed by the method provided by the embodiment of the present invention. The download is not performed by the mobile terminal that has transmitted a response that the download is too late and the mobile terminal that does not transmit the response within the set time after receiving the progress search request. If the new file waiting for download is relatively small, for example, if the number of bytes of the file is larger than the set minimum number of bytes of the file to be downloaded by the mobile terminal connected to the mobile terminal, direct file download A new download waiting file can be downloaded by a necessary mobile terminal.

  Of course, those skilled in the art can adopt other executable forms to realize the download of a new download waiting file, and each executable form will not be described here one by one.

  In an actual application, a reception completion response is sent to the mobile terminal that needs to download the file, and the mobile terminal that receives the file has received the reception completion response. May be. In this case, S103 may be as follows.

  That is, after receiving the reception completion response from the mobile terminal that receives the file, the sub-file received from the mobile terminal that transmitted the reception completion response is acquired.

  Furthermore, each file receiving mobile terminal can also acquire files downloaded by other mobile receiving terminals other than its own device, so that all the subfiles received by the mobile receiving terminal when the mobile terminal requiring file downloading is received. After obtaining the file, the mobile terminal receiving each file may be notified of the arrangement order of the mobile terminal in which other files exist and the sub-files waiting to be downloaded. The mobile terminal that receives each file may acquire all the subfiles and merge the subfiles into one file.

In the actual application, after the mobile terminal that needs file download has acquired all the subfiles, the file download method provided by the embodiment of the present invention further includes:
A mobile terminal information corresponding to each subfile and a notification message including the arrangement order of the subfiles in the download waiting file are transmitted to each file receiving mobile terminal. When it is determined that reception is necessary, all subfiles are acquired based on the notification message, and each subfile is merged into one file and stored.

  As shown in FIG. 4, the file download method provided by the embodiment of the present invention includes the following steps.

  S401: A download request is transmitted to each mobile terminal connected to the mobile terminal that needs the file download.

  S402: Until the waiting time reaches the maximum waiting time set based on the size of the file waiting for download, or when the number of mobile terminals that have received the file is determined based on the size of the file waiting for download. Receive the download acceptance response sent from each mobile device connected to the mobile device that requires file download until the maximum number of mobile devices is reached, and determine the mobile device that sent the download acceptance response as the mobile device that received the file .

  S403: Sending a download request for split download of a file waiting for download to the server, so that the server determines the number of subfiles waiting for download based on the proportional relationship of the sizes of the subfiles after splitting as many as the number of mobile terminals receiving the file. And each sub file is transmitted to the corresponding mobile terminal in the download / mapping relationship. In the split download request for the download pending file, the proportional relationship between the size of the download pending file and the size of the subfile after split determined based on the device performance and bandwidth of the mobile terminal receiving the file, and the size and file of the download pending file The sub-file after division determined based on the device performance and bandwidth of the receiving mobile terminal and the download / mapping relationship between the mobile terminal receiving the file are included.

  S404: Determine the download time of each file receiving mobile terminal based on the device performance of each file receiving mobile terminal.

  S405: If it is determined that a reception completion response has not been sent back from the mobile terminal receiving each file within the set download time, a download progress inquiry request is transmitted to the mobile terminal receiving each file.

  S 406: When receiving a response indicating that the download transmitted from the file receiving mobile terminal is too late, or from the file receiving mobile terminal within the set time after transmitting the download progress inquiry request to the file receiving mobile terminal Is not received, a download end command is transmitted to the mobile terminal that receives the file, and the corresponding subfile is set as a new download waiting file.

  S407: After receiving the reception completion response transmitted from the mobile terminal that has received each file, the sub-file received from the mobile terminal that transmitted the reception completion response is acquired.

  S408: After all the subfiles are acquired, the subfiles are merged into one file and stored.

  S409: Sending a notification message including mobile terminal information corresponding to each subfile and the order of arrangement of each subfile to the download waiting file to the mobile terminal receiving each file, and receiving the file by the mobile terminal receiving each file If it is determined that the file is necessary, all the subfiles are acquired based on the notification message, and the subfiles are merged into one file and stored.

  The download waiting file is divided into subfiles, and the divided subfiles are downloaded by the mobile terminals connected to each other. After downloading, the subfile is acquired from the mobile terminal connected to the mobile terminal, Merge and save to file. As a result, the mobile terminal can complete the file download in a short consumption time.

  The proportional relationship of the size of the subfile after division determined based on the size of the file waiting for download, the device performance of the mobile terminal receiving the file, and the bandwidth, and the download mapping between the subfile after division and the mobile terminal receiving the file When the download waiting file is divided and downloaded according to the relationship, the download task is divided based on the proportional relationship of the size of the divided subfiles and the download task is distributed based on the download mapping relationship. As a result, the progress of the entire download can be accelerated, and rational use of resources can be realized.

  When a response indicating that the download of the mobile device receiving the file is too late was received, or the response from the mobile device receiving the file was not received within the set time after sending the download progress inquiry request to the mobile device In this case, a download end command is transmitted to the mobile terminal that receives the file, and the corresponding sub file is set as a new download waiting file. This can accelerate the overall download speed.

  After all the subfiles are acquired, a notification message including mobile terminal information corresponding to each subfile and the order of arrangement of the subfiles in the download waiting file is transmitted to the mobile terminal receiving each file. As a result, when it is determined that the file receiving mobile terminal needs to receive the file, all the subfiles are acquired based on the notification message, and the subfiles are merged into one file and stored. Becomes convenient.

  As shown in FIG. 5, the file download apparatus provided by the embodiment of the present invention includes a first determination unit 501, a first transmission unit 502, an acquisition unit 503, and a merge unit 504.

  The first determination unit 501 determines at least one mobile terminal that receives a file from each mobile terminal connected to the device when the mobile terminal connected to the device needs to download a file. To do.

  The first transmission means 502 transmits a download request for dividing a file waiting for download to the server, and transmits the subfile obtained by dividing the file waiting for download by the server to the mobile terminal that receives the file, or receives the file. To the mobile terminal and the mobile terminal that requires file download.

  The acquisition unit 503 acquires the subfile received by the mobile terminal that has completed reception after the mobile terminal that has received the file has received and completed the file.

  The merger 504 acquires all the subfiles and then merges and saves the subfiles into one file.

  When a mobile terminal wants to download a file, if there are a plurality of mobile terminals connected to the mobile terminal, the download may be performed by the mobile terminal connected to the mobile terminal. In this case, the mobile terminal that needs to download the file may determine at least one mobile terminal that receives the file from among the mobile terminals connected to the mobile terminal.

  After the mobile terminal that needs to download the file sends a download request for dividing the file waiting for download to the server, the server sends the subfile obtained by dividing the file waiting for download to the mobile terminal that receives the file, or the mobile that receives the file. Send to terminal and mobile terminal that needs file download. For example, if the bandwidth of a mobile device that needs to download a file is relatively small, to improve the download speed, the mobile device that needs to download the file will not receive the file, and only the mobile device that receives the file will receive the file. You may receive it.

  After the file receiving mobile terminal receives and completes the file, the mobile terminal that needs to download the file may obtain the subfile received by the mobile terminal that has received the file. The mobile terminal that needs to download a file, after acquiring all the subfiles, merges the subfiles into one file and stores them. This makes it possible to download files. Since each mobile terminal downloads only one sub-file, the file can be downloaded to the mobile terminal in a short consumption time.

  Here, each mobile terminal connected to the mobile terminal apparatus may be a mobile terminal capable of realizing resource sharing by connecting to the scheduling mobile terminal apparatus via a wired or wireless system. The wireless connection may be a wireless connection with resource sharing between devices such as a Bluetooth connection or an adhocfi connection.

  In an actual application, a mobile terminal that needs to download a file may receive a subfile together with a mobile terminal that receives the file. For example, in order to reduce the amount of system processing and increase the download speed, a mobile terminal that needs to download a file does not receive the subfile, determines the mobile terminal that receives the file, and downloads the files that are waiting to be downloaded to the system. You may only send bills.

  As shown in FIG. 6, the first determination unit 501 includes a first transmission module 601 and a first determination module 602.

  When the mobile terminal connected to the mobile terminal needs to download a file, the first transmission module 601 transmits a download request to each mobile terminal connected to the mobile terminal that needs to download the file.

  The first confirmation module 602 determines whether the waiting time reaches the maximum waiting time set based on the size of the file waiting for download or the number of mobile terminals that have received the confirmed file is based on the size of the file waiting for download. Receive the download acceptance response sent from each mobile device connected to the mobile device that requires file download until the maximum number of mobile devices that receive the file is set, and receive the mobile device that sent the download acceptance response as a file Confirmed as one of the mobile terminals.

  Of course, those skilled in the art may implement the first determination means 501 by adopting other possible forms. Here, only one implementation is provided, and each possible implementation is not described one by one.

  Furthermore, since the performance and bandwidth of each mobile terminal are different, the download speed of a mobile terminal with good performance is faster than the download speed of a mobile terminal with relatively poor performance, and the download speed of a mobile terminal with a large bandwidth is Since the download speed of a mobile terminal having a relatively small bandwidth becomes faster, it is necessary to consider the device performance and bandwidth of the mobile terminal that receives each file when dividing a download waiting file and distributing a download task. In an actual application, when a download request for a download-waiting file is divided, the proportional relationship between the size of the download-waiting file and the size of the sub-file after division determined based on the device performance and bandwidth of the mobile terminal receiving the file The size of the file, the device performance of the mobile terminal that receives the file, and the download / mapping relationship between the divided subfile determined based on the bandwidth and the mobile terminal that receives the file may be included.

The server sends the subfiles obtained by dividing the file waiting for download to the mobile terminal that receives the file, or sends it to the mobile terminal that receives the file and the mobile terminal that needs to download the file,
The server divides the download waiting file into the same number of subfiles as the number of mobile terminals receiving the file based on the proportional relationship of the divided subfile sizes, and each subfile is associated with the mobile in the download mapping relationship. It may be transmitted to the terminal.

  For example, in order to guarantee the progress of the overall download and improve the overall smooth download speed, the apparatus provided in FIG. 5 further comprises a second determining means. The second determining means determines that there is a mobile terminal that receives a file whose download speed is too slow, or if it is determined that there is a mobile terminal that receives a file that is poorly connected to its own device. A download end command is transmitted to the file receiving mobile terminal which is too late or has a poor connection, and the corresponding sub file is set as a new download waiting file.

  In an actual application, a download time is set for each file receiving mobile terminal, and when the download time is reached, a download progress inquiry request is transmitted to each file receiving mobile terminal. If a response indicating that the download is too slow has been received or if the response of the mobile terminal that received the file within the set time has not been received, it is determined that the download speed of the mobile terminal is too slow and a download end command is sent. Then, the download of the mobile terminal is terminated, the sub file to be downloaded by the mobile terminal is set as a new download waiting file, and the download is performed again.

  In this case, as shown in FIG. 7, the second determination unit includes a second determination module 701, a second transmission module 702, and a third transmission module 703.

  The second determination module 701 determines the download time of each file receiving mobile terminal based on the device performance of each file receiving mobile terminal.

  If the second transmission module 702 determines that the reception completion response has not been sent back from the mobile terminal receiving each file within the set download time, the second transmission module 702 transmits a download progress inquiry request to the mobile terminal receiving each file.

  The third transmission module 703 receives the response that the download transmitted from the file receiving mobile terminal is too late, or within the set time after transmitting the download progress inquiry request to the file receiving mobile terminal. If a response from the file receiving mobile terminal has not been received, a download end command is transmitted to the file receiving mobile terminal, and the corresponding subfile is set as a new download waiting file.
